To use the Color Purity option, press the following keys:
To toggle the dialog box on and off, press the space bar.
To toggle a particular color gun on or off, press the appropriate
numeric key (1, 2, or 3). Angled brackets, for example <1>,
indicate the color gun is on.
To toggle the intensity of the selected color, press 4.
Table 13 shows how to produce each color by turning the color guns
on or off. For example, turn on red and blue to view magenta, or turn
on green and blue to view cyan.
When viewing a color with the Color Purity option, look for the color
to be uniform across all areas of the screen. Shading, shadows, and
distortion in the color indicate there may be problems with the video.
Some monitors have a Degauss button. If you notice any problems
with the color, try pressing the Degauss button to neutralize the
magnetic field that builds up on the CRT. Also, check that other
monitor controls, such as the Text button or terminating switches, are
set properly. For more information on these controls, refer to the
documentation on your particular monitor.
If there are still problems with the video, review the installation
procedure for the touchscreen and check that you reassembled the
monitor properly. Remember that a bad video indicates a hardware
problem with the monitor, not the touchscreen.
To exit from Color Purity and return to the Main menu, press Esc.
